Purchaser Concentration describes the extent to which a UK property development depends on a small number of buyers or pre-sale commitments. In property development finance, a high level of purchaser concentration is viewed as a significant risk because the withdrawal or failure of a single buyer can severely disrupt cash flow and jeopardise loan repayments. Developers and lenders carefully assess purchaser concentration to gauge the robustness and reliability of the sales pipeline, predict cash flow stability, and evaluate exposure to counterparty and market risks. Managing purchaser concentration is therefore crucial for maintaining project viability and securing financing.


This sits beneath Financial Resilience & Liquidity Indicators, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Counterparty Concentration Index, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Purchaser Concentration is most commonly encountered in connection with Soft Mini-Perm within the property development capital stack.
